Windows 10 and KIR

Lorenzo Fongaro 11 Reputation points

Good morning everyone.

I need some clarification about the KIR.

I installed on both Windows 2019 servers and Windows 10 PCs 21h1 the fixes you released a few days ago, namely:

Windows 10 (1809) & Windows Server 2019 Known Issue Rollback 091821 01.msi


Windows 10 (2004, 20H2 and 21H1) Known Issue Rollback 091721 01.msi

as a result of this fact for a few days on Windows is installed a package called

Known Issue Rollback Policy Definitions

Going to check the Windows policies you will find what you can see in the attachment.

Today you released an optional update called KB5005611. I immediately tried to install it to see the behavior of the package installed some days ago. No entries appeared in Group Policy in addition to the one you see in the attachment.

At this point I admit that I have not precisely understood how it works. Does the entry about disabling an optional update appear automatically after a Windows update after you have discovered some problems? As I understood it, the administrator could still choose to disable the installed patch at will.

Sorry for the somewhat long message.

I look forward to your reply.

Thank you and friendliness.136894-clipboard03.jpg

    Hi there,

    Yes as an admin you can still choose to disable the installed patch at will.
    You can use Group Policy settings or mobile device management (MDM) to configure the behavior of Windows Update (WU) on your Windows 10 devices. You can configure the update detection frequency, select when updates are received, specify the update service location, and more.
